4Be itknowntliat I,FRANKSToURAL, a citizen ofthe `United "States, residing `at `Verdigre, in the county V:of Knox andState of Nebraska, have :invented cer-tain new and 'useful' mprovenientsin Antiskid Devices, of which the following is a specification.

5 This invention relatesy to ycertain. neweand .useful improvements in anti-skid .devices of the type associated with vehiclewheels,and

:more particularly the treadsurfaces of pneumatic tiresfand-hasfoiits lprimary object to provide an adjustable clamping Adevice i for the `anti-skid `with 1 the latter :arranged in `spaced relations around a tire and wheel rim. A f.

A further-febject of the invention isto .provide an anti-skid `device wherein the means forianchoring the saine upon a wheel Aembodies a screw. adjustment toV accommodate the .device to tires and wheels of different diameters.

-With the abovezand other objects in view that willbeconie apparent as the `nature of the invention is better understood, the same consists of the novel forni, conibinationland arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.-

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 shows by dotted lines, a fragmentary side elevational view of an automobile :m wheel with the anti-skid device of this iiivention in position thereon,

Figure 2 is a front sectional View showing the anti-skid device in position upon the tire and wheel riin and the clamping devices 4o in locked position `with the anti-skid vfoot extending circumferentially of the tire,

VFigure 3 is a cross-sectional view similar to Fig. 2 showing the anti-skid foot extending across the tread of the tire, and

tional view of the anti-skid device.

lThe anti-skid device is associated with a wheel embodying a felly 1 and tire 2 mounted thereon and includes a metallic tread plate 3 of curved formation that encloses the tread surface of the tire 2 as shown in Figs. 2 and 3, the opposite ends of the tread plate being bent upon themselves and suitably secured to form eye loops 4. A rectan a5 guiar link 5 has one side thereof pivotally supported in one of the loops 4 and is of a Figure 4 is a fragmentary edge eleva-v niinate adjacent the wheel felly11. "Another link 6 of substantially triangular? formation lasv shownsin Fig. 4 has :one side' 'thereof pivotally supported in thefotherloopl-4swith the inner endlr thereof vterminating inwardly connected atk 8 to thefinner sidebar -ofjthe link 151and is adaptedwto-be positionedwin-` -llength to haveV the opposite side thereofvteril wardly of theifefllyA 1 as illustrated,- a'fabric r orfleather spacinginember 9: being-carried `by the outer faceof the plate?1 for fdirectly engaging the fellyV andf-tof pi'eventinjury thereto. Theiopposite side of the platel'iis bent @outwardly and is bent upon itself transversely ofthe plate 7 to forman-ear 10.

`A clamping arin 11 of angle formation as shown in Figs. `2 and?) is pivotally mounted Vupon the ypin 12 carried by the ear 10. The

clamping arm 11 is adapted tobe positioned beneath orinwardly ofthe fel-ly engaging plate when. in Iits Aclamped position :with the outer edge oftheclainping arm contacting thead'jacent faceof theplate'7. .The

inner edge of the `clamping arm. 11 isprovided with. I an` edge- .openinglsnotchi 13. vthat When the tread plate 3 is placed upon thc tire 2, the `arm 11 is swung laterally upon The free end of the clamping arm 11 ein` bodies a pair of spaced legs 14. between which an adjusting screw' and nut extend for locking the clamping arm in position, an eye bolt or scroll 15 having the eye end thereof inclosing the inner bar of the rectangular link 5 and freely passing through an opening in the adj acentend of the plate 7 with the lower threaded end 16 thereof projecting between the legs 14. A thumb nut 17 threaded on the eye bolt vor screw 15 is moved into engagement with the adjacent sides of the legs 14 to retain the eye bolt against movement'and to hold the clamping Hreceives fthe i adjacent f end off the link 6; f

bolt 15 therebetween.

arm 11 in its locked position `with the antiskid device secured upon the tire and Wheel telly. It being understood that the antiskid devices are arranged in spaced relation upon the tire as illustrated in 1, the aidjacentV ground engaging spurs or feet extend in opposite directions, the foot 18 yas shown in F ig. 3 extendingtransversely of the tire 2 While the toot 19 extends circumterentially of the tire at the center ot the tread portion thereof.

From the above detail description of the device,V it is believed that the construction and operation*thereoil will at 4once be apparent, it being noted that when the device is applied to the tire, the thumb nut 17 is loosened to permit discngagen'ient or the clamping arm 11 from the eye bolt 15 so that the clamping arm may be swung lat- Aerally to disengage the link -6 therefrom.

When the device is positioned in inclosing relations with a tire, the arm Vll is swung outwardly to receive the adjacent end off the link 6' in the edge notch 13 Ithereof and pivotal movement of the free end ofthe clamping arm in a direction toward the eye bolt will move the several parts of the device into intimate engagement with the tire Vand Wheel telly and position the spaced legs 14: ofthe clamping arm for reception of the eye V'Tith the yclamping nuts 17 adjusted 'for contacting the adjacent sides of the legs 11i, the anti-skid device is securely locked upon the Wheel and accidental displacement thereof is eliminated.

While thereis herein shown and described the preferred embodiment of the present invention it is nevertheless to be lunderstood thatfminor changes may be made therein Without departing from the spirit and scope of the invention as claimed.

lVhat is claimed as new is r1. In an anti-skid device, an arcuate tire engaging plate, a link carried by each side thereof, a. felly engaging plate to Which one of the links is pivot-ally attached at one side, a clamping arln pivotally attached to the other side of the telly plate and constructed for detachable engagement with the other link, a threaded bolti carried by the link adjacent the telly plate mounting, spaced legs at the treev end o the arm between which thebolt is positioned and a nut threaded on the bolt into engagement with the legs for holding' the clamping arm in closed position.

2. ln an anti-skid device, an arcuate tire engaging plate, a link carried by each side thereof, a telly engaging plate to which lone of the links is pivotally attached at one side a clam` ino` arm ivotall attached to the other side of the telly plate, the lower edge ot the arm having a notchtherein to detachably receive the otherlink, a threaded bolt carried by the link vadjacent the telly plate mounting, spaced` legs at the tree end of the arm between Which the bolt is positioned and a nut threaded on the bolt into .engagement with the legs for holding the clamping arm in closed position.
